Abstract
The fusidic acid(ent-16α-acetoxy-3β-dihydroxy-4β,8β,14α-trimethyl-18-nor-5β,10α-cholesta-(17z)-17(20),24-dien-21-oic acid) together with known compounds β-sitosterol, 2-methylanthraquinone, scopoletin, betulinic acid, corchoroside –A and cannogenol  from  the root extract of Corchorus olitorius. Out of these compounds, 2 - methyl anthraquinone and fusidic acids were new to the genus Corchorus and reported for the first time from C.olitorius. The triterpenoid antibiotic fusidic acid was  obtained earlier from a fungi (Fusidium coccineum) , is now reported from the plant C.olitorius.  Occurance  of coumarins in Corchorus genus are rare, but the author could isolate scopoletin, a coumarin from this species.

Abstract
A Quantitative Structure Activity Relationship study on a Series of 40 molecules of (4-Quinolylhydrazone compounds) with anti-tubercular activity analogues was made using combination of various physicochemical descriptors (Thermodynamic, electronic and spatial). Several statistical expressions for 2D QSAR & 3D QSAR were developed using stepwise partial least square (PLS) regression analysis and K-Nearest neighboring molecular field analysis (K-NNMFA) respectively. The studies on 2D-QSAR, suggested the four descriptors T_C_C_2, T_C_N_4, Surface area excluding P & S, SsCH3E-index, and H donor count were common and highly contributed the activity. 2DQSAR model developed using partial least square regression approach. Negative logarithmic value of (MIC) was taken as dependent variable and selected discriptors were taken as independent varable. The analysis resulted in the following 2D-equation suggest that, MIC50 = [+0.1587 T_C_C_2- 0.0593 SsCH3E-index- 0.1395 T_C_N_4+ 0.3888 H-Donor Count -3.1556], n =26; Degree of freedom = 22; r² = 0.75; q² = 0.67; F test = 22.63;  r² se = 0.20 ; q² se = 0.23; pred_r² = 0.46 ; pred_r² se = 0.24, a H-donor group at Ar, is important for guiding the design of a new molecule. 3DQSAR model developed using K-nearest neighbour method (training set =33 and test set = 7). The best model derived by the method have q2 = 0.51, q2_se = 0.25, Predr2 = 0.71, pred_r2se = 0.16, n=33, k Nearest Neighbor is 2, Degree of freedom =28. The steric and electrostatic descriptors at the grid points, E_916 (0.1865, 0.3006); S_591 (-0.2851, -0.2580); S_1027 (-0.3273, -0.3090); S926 (30.000, 30.000) plays important role for design of new molecule. 3DQSAR analysis of series of 4-Quinolylhydrazone compounds informed that electropositive and less bulky group increases the biological activity.

Gout is a kind of arthritis that occurs when uric acid builds up in the joints. Acute gout is a painful condition that typically affects one joint. Chronic gout is repeated episodes of pain and inflammation, which may involve more than one joint. Gout is a medical condition usually characterized by recurrent attacks of acute inflammatory arthritis—a red, tender, hot, swollen joint. The metatarsal-phalangeal joint at the base of the big toe is affected most often (condition also known as podagra¹), accounting for half of cases. Other joints, such as the heels, knees, wrists and fingers, may also be affected. Joint pain usually begins over 2–4 hours and during the night. The reason for onset at night is due to the lower body temperature then. Other symptoms that may occur along with the joint pain include fatigue and a high fever

1. INTRODUCTION
A peptic ulcer is a hole in the gut lining of the stomach, duodenum, or esophagus. A peptic ulcer of the stomach is called a gastric ulcer; of the duodenum, a duodenal ulcer; and of the esophagus, an esophageal ulcer. An ulcer occurs when the lining of these organs is corroded by the acidic digestive juices which are secreted by the stomach cells. Peptic ulcer disease is common, affecting millions of Americans yearly. The medical cost of treating peptic ulcer and its complications runs in the billions of dollars annually. Recent medical advances have increased our understanding of ulcer formation [1,2].

ABSTRACT
The family Cyperacea includes approximately 3000 species of which about 220 species are identified as weeds and of which 42% of these weeds are in the genus Cyperus. Both purple nutsedge (Cyperus rotundus L.) and yellow nutsedge (C. esculentus L.) are problem weeds in many parts of the world. Nutsedges originate from tropical and subtropical areas. . The plant produces rhizomes, tubers, basal bulbs and fibrous roots below ground, and rosettes of leaves, scapes, and umbels above ground.  C. rotutdus consists of rhizome and stolon having a number of wiry roots, stolon 10-20 cm long having a number of rhizomes, crowded together on the stolons, rhizomes bluntly conical and vary in size and thickness.The rhizomes are initially white and fleshy with scaly leaves and then become fibrous, wiry, and very dark brown with age. Purple nutsedge is readily distinguished from yellow nut sedge and other sedges by its purplish brown spikelets and scaly or wiry rhizomes that often bear chains of tubers.Phytochemical studies have shown that the major chemical components of this herb are polyphenol, flavonol glycoside, alkaloid, saponins, sesquiterpenoids and essential oil. Rhizome of the plant is used in fever,arthritis,diuretic, nervine tonic, treatment of diarrhea and dysentery ,leprosy, bronchitis, amenorrhea, and blood disorders. Leaves and seeds are rich in volatile oil and act on digestive system. Fruits are used as carminative , diuretic tonic, stomachic. Oil is fungicidal and bactericidal.

Abstract
Transplantation is the process of  removal of  damaged tissue or organ and replacing with new well functioning tissue or organ of same or different individual. The groundwork for the new science of transplantation immunology was laid by Medawar and other British biologists in the 1940s. They showed that rejection of tissue transferred from one person or animal to another was invariable, except for grafts between identical twins or a few special cases (e.g. cornea). In the 1950s they further showed that this tissue rejection was a response of the immune system. Other scientists who worked for transplantation are  Karl Landsteiner, Dr. Eduard Zirm, Dr. Alexis Carrel, Peter Gorer, Little and Tyzzer, George Snell, Dr. Joseph Murray etc..,Different types of organs like heart,skin,kidney,liver,cornea etc.., can be transplanted. Antigens which cause strong immune response and are most important in rejection of organs and tissues are called MHC antigens which play main role in transplantation. There are mainly 4 types of grafts. They are Autograft,Isograft,Allograft and Xenograft. The rejection may be acute and chronic and the mechanism of graft rejection is of mainly 2 types. They are sensitization stage and effector stage. Finally, the graft survival can be done by mitotic inhibitors, immune suppressive therapy etc..,

Abstract
Chalcone are the important constituent of many natural sources and have variety of biological activities. The novel chalcone derivatives isolated from the fruits of Mallotus philippinensis called mallotophilippens. The chalcones are synthesize by claisen-schmidt base catalyzed condensation of appropriate aromatic ketones or substituted aromatic ketones with benzaldehyde or substituted benzaldehydes. Chalcones, considered as the precursors of flavonoids and isoflavonoids, are abundant in edible plants, and have also been shown to display a diverse array of pharmacological activities. Recent reports suggest antimicrobial activity of chalcones (antibacterial and antifungal), as well as antileishmanial, antimalarial, antiviral and anti-inflammatory activities of these compounds.

ABSTRACT
Aceclofenac and paracetamol in combination are available as tablet dosage forms in the ratio of 1:5. A simple, reproducible and efficient method for the simultaneous determination of aceclofenac and paracetamol in synthetic mixture was developed. The proposed method is based on the Q-analysis UV Spectrophotometric method. The absorbance maxima of aceclofenac and paracetamol were found to be 275.4 nm and 248 nm, respectively in methanol. In Q-analysis, the isoabsorptive point for both the drugs was found at 266.1 nm. The linearity range lies between 1-35 µg/ml for aceclofenac and 1-15 µg/ml for paracetamol at their respective wavelengths. Both the drugs obey Beer’s law. The recovery studies confirmed the accuracy of the proposed methods.
